UNITED STATES PATENT OFFICE ANDREW MARTIN AND JOHN JOHNSTON, J'R., OF ESCONDIDO, CALIFORNIA PROCESS OF PRODUCING FERTILIZER COMPOUNDS No Drawing. Application filed October 28, 1926. Serial No. 144,914.

Our invention relates to humus fertilizer The humus fertilizer is prepared as compound and a process for making humus follows: fertilizer, and the objects of our invention The garbage, which may be any refuse, are first, to provide a humus fertilizer which vegetation or vegetables, may include animal 6 is made of Waste or refuse products; second, matter Without injury, which produces amore 55 to provide a humus fertilizer compound, the effective fertilizer. This garbage is ground ingredients of which are plentiful in all fine enough to pass through a one-quarter localities; third, to provide a humus fertilizerh 1955- T the f l Placed compound which is very eflicient and effective, sultahle fermenting Whlch 15 Wateroontaining the necessary ingredients for tlght but Open on pa ahd'let stahd- It 50 d h d f H f t} is preferred to have a vat about eight feet 2 3 gi g i i g m? ii 36 233 3 deep and 1t should be filled about two-thirds full.

the compound and rocess substantially as set forth in the appen ed claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. The herein described method of producing humus fertilizer, consisting in grinding garbage fine; then fermenting the mass ten days to two weeksin an open top vat, a 'tating the mass every twenty-four hours, eeping the mass warm and then mixing the mass with an equal amount of sawdust.

2. The herein described method of producing humus fertilizer, consisting in grinding garbage fine; then fermenting the resultant wet mass ten days to two weeks in an open top vat; and then mixing the mass with'an equal amount of sawdust.

3. The herein described method of producing humus fertilizer, consisting in grinding garbage; then fermenting the resultant wet mass, addin water from time to time to keep it in liquid orm, keeping the mass warm, and then mixing the mass with an equal amount of sawdust and shavin e.

4. The herein descriidied method of producing humus fertilizer, consisting in grinding garbage; then fermenting the resultant wet mass, adding water from time to time to keep it in liquid form, keeping the mass warm; then mixing the mass with an equal amount of sawdust and shavings; and then piling the mass up and letting it stand for three weeks or more.

5. The herein described method of producing humus fertilizer, consisting in grinding garbage; then fermenting the resultant wet mass, adding water from time to time to keep it in liquid form, keeping the mass warm; then mixing the mass with an equal amount of sawdust and shavings; andthen mixing in a quantity of nitrate of soda, being about twenty percent of the mass.

6. The herein described method of producing humus fertilizer, consisting in grinding garbage fine enough to pass through a quarter-inch screen then fermenting the resultant wet mass in a vat which is watertight and open on the top, keeping the mass warm then after fermentation starts adding water to keep it suitably liquid; then agitating the mass eve twenty-four hours, letting it stand from ten ays to two weeks; then aerating the mass if the temperature of the atmosphere is cool, heating the mass; then mixing the liquor from the mass. with sawdust and small shavings; then intermingling the solidmatter left from the mass with the saturated sawdust and shavings and liquor; and then piling the mass and keeping it damp, letting it stand three weeks or more.

7. The herein described method of producing humus fertilzer, consisting in grinding garbage fine enough to pass through a uarter-inch screen; then fermenting the resu tant wet mass in a vat which is watertight and open on the top; then, after fermentation starts, adding water to keep it suitably liquid; then agitating the mass every twenty-four hours, letting it stand from ten days to two weeks; then aerating the mass, if the temperature of the atmosphere is cool, keeping the mass heated; then mixing the liquor from the mass with sawdust and small shavings; then intermingling the solid matter left from the mass with the saturated sawdust andshavings and liquors; then piling up the mass and keeping it damp, letting it stand three weeks or more; and then adding nitrate of soda in the amount of twenty per cent of the whole mass.

8. The herein described method of producing humus fertilizer, consisting in grinding garbage fine enou h to pass through a quartor-inch screen; then fermenting the resultant wet mass in a vat which is'watertight and open at the top; then after fermentation starts adding water to keep it suitably liquid; then agitating the mass every twenty-four hours, letting it stand from ten days to two weeks; then aerating the mass; if the temperature of the atmosphere is cool, heating the mass; then mixing the liquor from the mass with sawdust and small shavings; then intermingling the solid matter left from the mass with the saturated sawdust and shavings and li uor; then piling up the mass and keeping it amp and warm, letting it stand three weeks or more; and then adding other fertilizer to suit.

In testimony whereof, we have hereunto set our hands at Escondido, California, this 22nd day of October, 1926.
